To all whom may concern y Be it known that I, ELIHU BowLiN, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and l.

State of'Tennessee, have invented new and useful Improvements in Reversible VDisk Flows, of which the following is a speciication.

rIhis invention relates to reversible disk plows and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a plow comprisingv a wheel mounted frame with a head turnably mounted thereon and of special design, there being a standard and soil engaging element carried by the head.

In the accompanying drawings :e-Figure 1 is a top plan view showing the parts of the plow in one position. Fig. 2 is a similar view showing the parts of the plow in another position. Y Fig. 3 isa transverse see-v tional view of parts ,of the plow. Figz is a perspective view of the parts shown in Fig. 3. Fig. 5 is a perspective view of means provided upon the plow for carrying the land wheel. Fig. G is a detail side elevation of a part of the plow with parts in section. Fig. Z is a detail sectional view of one of the furrow wheel supports of the plow.

The frame of the plow includes a beam 1 having angularly'disposed end portions 2. An approximately semicircular beam 3 is provided at one side of the beam 1 and is disposed at the opposite side of the inter-A mediate portion of the beam 1 from the end portions 2 of the said beam 1.

A bracket 4 is provided at the side of the beam 1 at a point midway between the ends of the beam 3 and at the opposite side from the said beam 3. The said bracket 4 is prcvided at its top side with an arcuate groove 5 and at its outer and upper'edge with a socket 6 having an arcuate inner vertical wall. The arc of the groove 5 and the arc of curvature of the wall of the socket 6 are approximately struck fromthe same center as the arc of curvature of the beam 3.

A block 7 is provided at the side of the beam 1 and a tongue 8 is pivotally mounted upon the said block at a point approximately at the center of the arc of curvature of the beam 3 and the said tongue extends transversely across the beam 3. A tooth 9 is provided at the inner or rear end of the tongue 8 and the said tooth is radially disaxle `10 at a posed with relation to pivot upon which the tongue swings and is also in alinementA withthe median longitudinal dimension of the tongue. An axle `10 is pivoted to the beam 3 at a point midway between the ends thereof and the said axle isprovided at its inner portion witha longfitudinallyidisposed slot 11. A pin 12 is provided upon the tongue 8 and enters the said slot l1 and is adapted to move along the same when the tongue Slis swung over the beam 3. A land wheel 13 is Journaled at the outer end of the A point 'beyond the outer side of the `beam 3.` The land wheel 13 may be Journaled upon a crank spindle 14 which in turn may be secured to the faxle 10 and thus means is provided for adjusting the center of the land wheel 13 axle 10 andbeam 3. When it is desired that the beam 3 should be positioned relatively close to the `ground the crankof the spindle 14 is positioned to oneside or the other of the axlez 10 andconsequently the center of the land wheel 13 is in close proximity to the beam 3. `When itis desired that the beam 3 'should be positioned at an elevated` point with relation to the' ground the crank of the spindle 14 is positioned immediately below the axle 10. Any suitable securing device may be provided for holding the spindle 111 at an adjustedposition with relation to the axle 10 as shown in Fig. 5 of the drawing.

A head 15 is mounted upon the bracket l and is provided at its under side with anges 16 which enter the'l groove 5 and socket 6. The outermostlange 16 is provided at its inner side and 17 in which a shoulder 18 provided uponthe curved wall of the socket 6 snugly lits. The

head 15 isprovidedat its outer end with a vertically disposed groove 19 having converging side ,walls.l A standard 20 is slidably mounted in the groove 19 and is provided with chamfered edges adapted to fit` snugly against the converging side walls of thepsaid groove. Adisk 21 is journaledl for rotation at the lower portion of the standard-,20. A lever 22 is fulcrumed` upon the:

head `15 and its working end is pivotally connected with the standard 20. By swinging the lever 22 the disk 21 may be raised above the surface of the soil and hence the tongue may be readily turned around at the end of a furrow.

with relation y to thev for instance that upper portion with a recess One end ofa link 23 is pivotally connected 1 with the tongue 8 at one sideof the point Y atwhic'h 'the'saidtongue ispivotally connected with the block 7y 'and the other` end of the said link 23 is pivotally connected with the head 15 at a point within the inner most flange '16. The head 15 is provided at vits Vinner end with 4apair of' teeth 24 which are adapted to receive between them vthe tooth 9 as the tongue is swung over` the beam 3.

, Brackets 25 aremounted upon the 4angullarly disposed end portionsy 2 of the beam 1 and a shaft 26 is journaled in each bracket 25. The shafts 26 carry at their lower ends spindles 27 upon which furrow wheels 28 arejournaled. Arms 29 are secured to the upper portions of the'shafts 26 at points*V abovethe bracketsV 25 anda bar 30V pivotally connects' the inner ends of the armsV 29 `together.` TheY intermediate portion of the bari 30 is pivotally connected with ythe link y 23'and the head 15 at the point of pivotal connection between the said link and head.

'An'operators seat 31 is mounted upon the inner end of the tongue 8 and the said tongue is provided with a pivotedrclip 32 which is adapted-to enter notches 33 provided at the end Vportions of the beam'- 1.`

The operationV of the plow is asfollows:

When the operator who occupies the seat 31 depresses'one end of the clip 32 the said clip is disengaged from one of the notches 33 and then the draft animals which are connected ywith the tongue 8 are driven around the'` outer side of the beam 3. Thus the free end of the tongue 8 is swung around the beam 3i vand the link 23 is moved longitudinally. Thisv movement on the part of the link 23 'will turn the head 15 upon the Vblock 7 and y'the turning movement on vthe part of the head will reverse the position of the standard 2O and disk 2 1 with relation to the beam 1. As the tongue v`Sand head 15 turn as kabove indicated the tooth 9 carried at the endgof the tongue will enter the space between the teeth 24=`provided upon the head and consequently when the tongue 8 is moving lalongvth'e intermediate portion of the beam V3 the said tongue is positively con nected lwith the head by'reason of the said.

intermeshing teeth andthe link 23 is assisted in, imparting aL turning movement to the head. During the time that the tongue 8 is Y moving from one end ofthe beam 3 to the other'the pin .12 carried by the said tongue and which is received within the slot llfof the a'Xle 10 will swing the said akle 1 and 3 are component parts.

described the bar 30 will be given a similar movement which in turn will swing the arms 29 and'inasmucli as the said arms are fixed to the shafts 26 the said shafts are turned in the brackets 25 whereby the furrow wheels carried at the lower ends of the shafts 26'are turned with relation to the frameof which the beams 1 and 3 are components. Therefore it will be seen that during the time that the disk is reversed from one position to another with relation to the frame of the plow the furrow wheels and the land wheel arey simultaneously swung or turned in order that theymay be properly positioned vwith relation to the frame and the line of draft as the direction of the tongue is changed with relation to the frame.

Having described the invention what is claimed is 1. A plow comprising a frame having a bracket provided with an arcuate groove which opens at its ends at the ends of the bracket, a head having a flange slidably received in the groove, a standard carried by the head and a disk carried by the standard.

2. A plow comprising a frame provided with a bracket having an arcuate groove and socket open at their ends, a head provided with fianges which enter the groove and the socket', one of the said flanges bcing provided with a recess, the wall of the socket having a shoulder which enters the recess, a standard carried by the head and a disk journaled upon the standard.

3. A plow comprising a frame, a head turnably mounted thereon, a soil engaging element operatively connected with the head, said head being provided at its inner end with a pair of spaced teeth, a tongue pivoted upon the frame and provided at its inner end with a tooth adapted to enter the space between the teeth of the head and a link pivotally connected at one end with the tongue and at its other end with the head.

In testimony whereof I affix my signature in presence of two witnesses.
